Plans to transform the south side of Birmingham are making positive progress this week following the submission of a planning application for a new landmark building which is set to complete The Mailbox development.

Designed by internationally renowned architect Ken Shuttleworth, the mixed use building - The Cube - will transform the former foundry and engineering works into what will become one of the city's most important waterside locations.

Plans for The Cube - thought to be costing around £100 million - are now with the city council for consideration.

If approved, the 500,000 sq ft site will be turned into a 17 storey building which will house more exclusive restaurants, apartments, hotels and offices.

Proposals include improved 24 hour access from Commercial Street into The Cube, The Mailbox and the Convention Quarter beyond; a rooftop restaurant with panoramic views across the city and a 'boutique hotel' of just 50 beds set to rival the best in the capital.

Alan Chatham, director of Birmingham Mailbox and Birmingham Development Company (BDC), said: "The Cube will become the 'jewel in the crown' of Birmingham's continued redevelopment.

"With a myriad of towers around us, The Cube will stand out on the Birmingham skyline and we hope will become a focal point of pride for Midlanders.

"The prime location and landmark building will see The Cube becoming the best address in the city."

The planning application has been submitted in record time; MAKE were only appointed in June, yet a design team has already been appointed to work with them and together they are working to ensure work can commence as soon as they get the green light.
